Blocked drains can quickly become unpleasant, inconvenient and, if left unresolved, potentially damaging to your property.
At Centra, we provide a complete range of drainage services for homes, landlords and businesses. From a blocked kitchen sink to damaged underground drainage, our team has the specialist equipment and experience needed to diagnose problems and get things flowing properly again.
We believe in straightforward advice, good communication and leaving your property clean and tidy once the work is complete.
Centra already provides both domestic and commercial drainage services and uses specialist equipment including CCTV inspection systems and high-pressure jetting equipment.
We can tackle everything from smaller household blockages to stubborn obstructions deeper within your drainage system. Common signs include slow draining water, unpleasant smells, gurgling noises, overflowing drains and water backing up through toilets, sinks or showers.
A blocked toilet or sink can quickly put an important part of your home out of action. Our drainage team can help clear blockages affecting toilets, kitchen sinks, basins, baths, showers and internal waste pipes, with as little disruption as possible.
When the cause of a problem isn't obvious, a CCTV drain survey lets us take a closer look underground without immediately having to dig. Specialist drain cameras can help identify: Recurring blockages | Cracked or collapsed drainage | Displaced joints | Tree root ingress
Our high-pressure drain jetting equipment can tackle stubborn obstructions and clean further along the drainage system. Jetting can help remove accumulated grease, fat, silt, scale, debris and other materials restricting the flow of a drain. It can also be used as part of planned drainage maintenance to help prevent future problems.
We can help with both above-ground and underground drainage, from localised repairs through to more substantial pipe replacement and excavation work. Where suitable, no-dig repair methods may also allow damaged sections of drainage to be repaired without digging up large areas of your property.
Centra can undertake drainage installation and replacement work for residential and commercial properties. Our team has experience with groundworks, drainage pipe replacement and older pitch fibre drainage systems, as well as smaller drainage alterations and repairs.

Buying a property?
A homebuyer CCTV drain survey can help identify hidden problems within underground drainage before you complete your purchase.
The survey can reveal issues such as cracked pipes, displaced joints, tree roots, collapsed sections, recurring blockages and ageing drainage materials that may otherwise go unnoticed.
Homebuyer drainage surveys are part of the existing drainage service offering.
Centra also provides professional drainage services for businesses, landlords and commercial properties.
From blocked drains and emergency problems to CCTV surveys, repairs and planned preventative maintenance, we can help keep commercial drainage systems working properly and reduce the risk of unexpected disruption.
See how we keep a local retail park running smoothly with out-of-hours drainage maintenance.


A recent CCTV drain survey at a property in Swindon revealed tree roots growing inside the drainage pipework. Roots can obstruct the flow of water and trap other debris, so it was important to clear the affected section of drain.
Our team used a specialist root cutting machine to remove the growth, followed by high pressure drain jetting to flush away the remaining debris. Once the work was complete, the drains were flowing freely again.
This job shows how a CCTV drain survey can help pinpoint the cause of a drainage problem and guide the next steps.

We can safely inspect, diagnose the issues and clear your gutters safely from the ground. Our high-powered gutter vacuum system allows us to clear gutters that are otherwise inaccessible.

Answers to common questions about blocked drains, CCTV surveys and drain repairs for homes and businesses in Swindon & Wiltshire.
Slow draining water, gurgling noises, unpleasant smells, water backing up and overflowing outside drains are all common signs of a blockage.
Yes. Centra can clear blocked toilets, sinks, baths, showers and other internal waste pipes as well as external drainage.
This can indicate a blockage further along the main drainage pipework. Wastewater is unable to flow away properly and can begin backing up through another opening in the system. This should be investigated quickly.
Yes. CCTV surveys allow us to inspect underground drainage and identify problems such as blockages, damaged pipes, displaced joints, tree roots and collapsed sections.
It isn't compulsory, but a homebuyer drain survey can identify hidden drainage problems before you purchase the property, particularly where there are older drains or signs of previous drainage issues.
In some situations, yes. No-dig repair techniques can be used to repair certain faults without traditional excavation. We would first need to assess the condition and location of the damaged pipework with a CCTV survey. See how we fixed a damaged pipe with a no-dig drain repair at a local home.
